ABSTRACT:
Disclosed is a lawn mower having several pairs of rotatable blades attached to a rotatable frame. The rotatable frame is motor driven, and centrifugal forces cause a frictional engagement between blade driving means and a portion of the frame so that each pair of the blades assume a planetary rotary motion, yet are capable of movement away from obstacles. Each pair of blades consists of two overlapping circular blades that are in frictional engagement with each other and rotate in opposite directions to effect a cutting action.
